Modular Coiled Tubing Unit with Adjustable Guide Posts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing weight demands of coiled tubing units due to longer, larger diameter tubing with thicker walls in the oil and gas industry, combined with varying roadways' axle weight distribution requirements, necessitate a configurable load distribution system for coiled tubing units.
Innovation Solution
A coiled tubing unit with a modular design featuring a load supporting skid frame and a reel skid landing platform, where guide posts and sleeves allow for adjustable positioning and securement, enabling multiple load configurations by shifting the weight distribution across different axle groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If coiled tubing units use longer, larger diameter tubing with thicker walls, then the tubing capacity and strength are improved, but the weight demands on the unit increase
Solution Approach 1:
The coiled tubing unit is divided into modular components including multiple skids (reel skid, pump skid, etc.), with the reel skid further segmented into frame, landing platform, and guide post assembly sections. This segmentation allows independent optimization of each module's weight and strength characteristics.
Solution Approach 2:
The guide posts are made movable along the landing platform beams, allowing dynamic repositioning to adjust weight distribution. This dynamic adjustment enables the unit to adapt to different road conditions and weight limits without changing the overall structure.
2Adaptability or versatility
If the coiled tubing unit uses a fixed weight distribution design, then the structural design is simplified, but it cannot meet varying axle weight requirements of different roadways
Solution Approach 1:
The guide posts are designed to be movable along the landing platform beams rather than fixed, allowing the reel skid position to be adjusted dynamically. This enables different weight distributions on the trailer axles while using the same basic structural components.
Solution Approach 2:
The landing platform beams serve multiple functions: they support the guide posts, provide structural rigidity, and act as rails for positioning the reel skid. This multi-functionality reduces the need for additional specialized components.
3Adaptability or versatility
If guide posts are made movable along the landing platform, then load distribution can be adjusted, but the securing mechanism becomes more complex
Solution Approach 1:
The guide posts have different properties at different locations: the lower portion is smooth for sliding along the beams, while the upper portion has engagement features for securing. This local differentiation simplifies the overall mechanism by combining sliding and locking functions in a single component.
Solution Approach 2:
The guide posts can be manually positioned and secured by the operators without requiring complex external securing mechanisms. The engagement features on the guide posts work with simple slots in the beams to provide self-contained positioning and securing functionality.

AI summary
A coiled tubing unit includes a coiled tubing reel skid comprising a load supporting skid frame having a plurality of guide post sleeves and a reel skid landing platform comprising a plurality of guide posts that mate with the plurality of guide post sleeves, wherein mating of the guide posts with the guide post sleeves is configurable so that the coiled tubing reel skid is disposable at multiple positions on the landing platform. The coiled tubing unit is configurable for many different weight distribution requirements.
